SPECIFICATION forming part of Letters Patent No. 424,386, dated March 25, 1890.

Y Application tiled June 18, lBBS. Serial No, 277,450. (No model.)

T0 LZZ whom it may concern:

Be it known that I, GOTTLITEB IVABNER, a citizen of the United States, residing at Glassborough, in the county of Gloucester and State of New Jersey, have in vented certain new and useful Improvements in Glory-Hole Furnaces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the art of making glass bottles, and more particularly tothe construction of furnaces, or what are technically calle( glory-holes, used in the iinishing of bottles.

The object of my invention is to supply means for overcoming certain disadvantages inherent in the coal-furnace-such as the inability to regulate easily the temperature at the glory-holes, dust, cinders, and smoke-and to produce a portable furnace which shall be simple in construction, durable, and effective and cheap in operation, and which shall have glory-holes capable of affording a degree of heat fully under the control of the Workman.

To these ends my invention consists in the general and specific combination, construction, and arrangement of parts, as hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, and in which like letters of reference designate corresponding parts, Figure l is a perspective view of my invention, showing a metal frame having legs of convenient height and supporting` a box made of metal and lined with'refractory material and bolted to the frame, also showing two reverberatory fire-chambers placed in the box back to back and face-plates situated in front of said nre-chambers, having apertures serving as glory-holes, also showing the oil tanks and pipes leading the oil and compressed air to the burners, (not shown,) also showing the slotted extensions of the frame provided with adjustable sliding rests adapted to support the pontil-rods, and showing a bottle attached to its pon-til-rod and having its neck inserted in the glory-hole. Fig. 2 is a perspective view of the frame and legs, showing the extensions provided with slots for the reception of the bolts of the adjustable sliding rests, also showing the holes in the flange enabling the lire-chamber box to be bolted to the frame. Fig. 3 is a perspective View of the fire-chamber box inverted, showing flanges adapting it to be b'olted to the frame. Fig. 4 is a perspective view of one `of the recham bers, showing the aperture for the reception of the burner leading into a recess in the interior of the chamber where the oil is ignited. Fig. 5is a side view, in section, of the furnace, showing the firechambcrs in position in the box, the faceplates, and the dispositionof t-he burners and air and oil pipes, (the latter being broken off.) Fig. 6 is a view of a burner consisting of an air-tube having a tapering point through which passes the end of an inner tube carrying the oil and projecting slightly from it.-

Fig. 7 is a view of a burner constructed differently from the one shown in Fig. 6, the airtube being rounded at the end and perforated with small apertures, and an inner tube carrying the oil brought to within a small distance of the perforated end of the inclosingtube. Fig. 8 shows aburner differing in construction from the other two and in which the air-tube tapers slightly at the end, the oiltube being placed outside and bent so as to present a line of current at right angles to that of the air. Y

In the art of making glass bottles the method usually adopted is to heat the glass until it acquires the necessarily-plastic condition, after which a suitably-sized portion of it is taken on the end of a long tube, rolled on a smooth surface to give it approximatelythe desired shape, and th en placed between the two halves of a heated mold and'expanded by means of the breath blown into the tube until the glass conforms to the shape of the mold, the mouth of the bottle adhering to the end of the tube. It is then withdrawn from the mold, the bottom part is attached to a rod called a pontil, and the neck is cut from the tube. The last process before annealing the bottle is to round off the sharp edgesV of the mouth. For this purpose the mouth of the bot-tie is placed in a furnace through an aperture called a gloryhole, where it isriinished, and asthis -now requires practice and careful manipulation to prevent blackening and burning, the means now commonly at the disposal of the workman being found ineffective, I have invented the furnace illustrated in the iigures above described to provide a more eifective and more easily-operated device that willprevent the loss to the manufacturer which accompanies the deterioration ofthe bottles above mentioned.

Different qualities of glass requiring different degrees of heat, it is found very difficult in practice to prevent the bottles blackening and burning while in the glory-holes, there being no means of regulating the heat at the glory-holes of the furnaces now in use.

In the drawings, A designates the supporting-frame, having the extensions a a2 a3 on one side and the slots d4 a5 a in them `and similar slotted extensions on the other side of the frame.

The letter a7 designates the legs.

B represents the fire-chamber box, which may be made of metal lined with clay, and has the Iianges h for the purpose of bolting it down to the frame A through the bolt-holes b2, the guides b3 for holding in place the faceplates, and the apertures b4 in the iioor of the box for the reception of the burner-tubes.

C represents the face-plates, the front being of sheet-iron c and lined with tire-clay c2.

c3 represents the glory-hole; c4, the recesses covering the elbows of the burner-tubes.

D representsl a fire-box, which is made of fire-clay and shaped as shown in Figs. 4 and 5. The iioor of .the chamber is fiat and has the recess d2 cut in it, extending from the back of the interior of the chamber, where the recess slopes upward, to within a short distance of the front, at which point it communicates with the outside by an orifice d. The fire-chamber is open in front, and the interior at the back gradually slopes downward, presenting in vertical section the appearance shown in Fig. 5.

It is intended that the burner be introduced in the oriice cl', so that ignition may take place in the recess cl2, and, as the latter is sloped upward, the flames, driven by the compressed air behind them, will naturally take the same direction and follow .the slope of the back and roof of the crucible until they impinge upon the face-plate C, which covers the mouth, and issue by the gloryholes c3 c3. It will be noticed that there are two glory-holes to each fire-chamber, and that there are two such tire-chambers in the box, placed back to back. This arrangement is for the convenience of the iinisher,who stands beside his glory-hole, and who may operate two pontil-rods at the same time.

, E represents the oil-cans, of which there may be any number.

e is a spigot to regulate the amount of oil issuing from the tanks.

e2 represents the catches, by means 'of which the can is hung-on the box; but any other manner of holding the oil-cans in position may be adopted in practice.

e3 is the oil-pipe leading to the burner and provided at the other end with a funnel into which the oil may run. Should it be found in practice that the heat is too great for the safety of the oil, the cans may be placed at a distance and the oil-pipes be elongated ac- .vided with stop-cocks f2, enabling the workman to reduce or increase the amount of air to his burner, and which, together with the spigot on the oil-can, will provide for an even and effective regulation of temperature at the glory-holes.

Gr represents the adjustable pontil rest placed nearest the glory-holes. Itis provided with downwardly-projecting arms at each end, adapted to travel in the slots of the extensions d and a, and each arm has two jamnuts g. The apertures g2 in the jam-nuts permit the use of a key for the purpose of setting the rest at any desired position.

H is a second pontil-rest placed farther back from the glory-holes and set upon a threaded post adapted to slide in the slot a4 of the extension a', and provided with a key 7L below the extension and a jam-.nut h2 above, permitting the rest to be adjustable both vertically and horizontally.

K represents one of the burners,which consists of an outer tube 7c', having a tapering point k2, and an inner tube 7c3, entering it at a convenient point, the joint being made airtight and extending to the end of and ashort distance beyond the outer tube. The air passes through the larger outer tube 7c', and the oil through the inner tube 7c3. The oil being ignited at the end 7t2,and the air turncd on, the latter will cause a thorough combustion and produce a iiame of great intensity.

Another form of burner is shown in Fig. 7, in which the outer tube h4 has a closed rounded end kf", perforated with small apertures. The oil-tube k6, introduced in the larger tube, eX- tends to wit-hin a short distance of the said apertures. This construction causes the air which is admitted through the outer tube to combine with the oil before ignition and may produce a more perfect combustion.

In Fig. S the oil-tube k7 does not enter the air-pipe 70S, but is extended alongside of it until it reaches the end, where at lo it makes an abrupt turn at right angles to the path of the currentof air.

The assembling of the different parts of the furnace is as follows: The frame being set up on its legs, the iire-chamber box is bolted to it and the cans filled with oil attached to it. The ire-boxesare placed in position, back to back, in the box, and the face-plates in the guides, with the] thin fire-clay lining toward the mouths of the crucibles, the burners ad- IOO justed in the apertures in the crucibles, and the pipe-connections made up. The sliding rests are placed in their respective slots and the jam-nuts screwed tight. The furnace is now ready for operation. The finishers stand beside the pontil-rests, each taking care of one or two glory-holes, and proceed to finish the mouths of the bottles that have been blown.

I do not restrict myself to the specific construction of the furnace as hereinbefore described, for it is evident that many changes may be made therein. Instead of two firechambers, one or any number may be used, and the form of the furnace may be round instead of square, and the fire-chambers arranged in a circle. The chamber and faceplate being separate, it will be found easier to clean and to adj ust the points of the burner at the proper place in the channel.

I-Iaving thus fullydescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a glory-hole furnace, the combination ot' one or more reverberatory fire-chambers, burners placed therein provided with oil and air pipes, and a series of interchangeable removable face-plates severally provided with apertures of different sizes to serve as gloryholes and adapted to be severally placed in front of said fire-chamber, substantially as described.
